Today I've uploaded a patch the fixes some issues with potions not being permanent.
For example if you had 4 potions when activating a checkpoint and then you gained 3 more but died you'd go back to 4 potions while it should have been 7.
Another fix that happened was now taking screenshots with F12 while Steam is active it doesn't creates two screenshots anymore.
These updates - as well as any previous ones - have been applied to the demo as well.
Keep being awesome,
